Global military spending
Total world spending on armed forces
$2,887,000,000,000
This year · 2025
What this number is
What the world's governments spend on their militaries in a year.
Total global military expenditure in current 2025 US dollars according to SIPRI. Reported defence budgets plus estimates for states that do not publish full figures.
Why it matters
Military spending is the most direct measure of how much of the world's money is committed to force.
How it is produced
National budget documents, harmonised and estimated where reporting is incomplete.
Plato's Cave classifies this figure as ESTIMATED. Estimated figures are built from samples and surveys, then scaled up. They carry a margin that is rarely printed alongside the headline.
How to read it carefully
Only one credible source currently supports this figure. It is reported here as a single-source claim, not a settled fact.
Reference period: 2025. Last checked: Sep 8, 2026.
Plato's Cave commentary
Military numbers are among the best funded statistics in the world. Governments count what they spend on weapons far more carefully than what they spend on the people the weapons are meant to protect.
That imbalance is itself the story. When a figure this large is uncontroversial, the argument is never about the data. It is about who decided the priority.
